Function description:
The heater is designed for accumulation heating of service water using electricity. Water is heated by an electric
element in an enamelled thermally insulated tank at the time defined by the power supplier. The element is at the time
of heating controlled by a thermostat the temperature of which can be adjusted continuously (within the range between
5°C and 74°C). Once the selected temperature is reached, heating interrupts automatically. Water accumulated in the
tank is then used for consumption.
1.1
Hot water consumption
Consumption of hot water in households depends on the number of people, amount of sanitary equipment, length,
diameter and insulation of piping in the flat, or on individual habits of users. The cheapest option of water heating
comes at the time when the electricity rate is reduced. Find out in what time intervals your electricity supplier
provides reduced tariff and, depending on that information, select relevant volume and power input of the heater so
that your hot water consumption covered the needs of your household.
